I'm going to be rather vague about this and it won't include replacing the seals but I think I have read that the front part of the seal frame should be sealed off from the outside by a mastic like Dum-Dum. That's NLA but there are alternatives. If this sealant is missing the airflow gets directed through the gaps and causes whistles and noise. Can anyone confirm this? Maybe they have come across the sealant when removing the QL. It might have hardened/dried up and wasn't replaced. Info wanted.
Not having door mirrors does keep things quiet in that area as they are notorious for disturbing the airflow around that corner.
